The protagonists were introduced to Admiral Thorn when their mutual contact, Gorn Vorrox arranged for them to meet and do business regarding the Jedi artifacts found on Jiroch. Thorn purchased the artifacts and showed off his Jedi museum, including the broken light saber hilt and crystal of Jedi Master Alesca Timmat.

Somehow Genarus Thorn had previously discovered Callia as a Jedi in exile and was using that knowledge to black mail her into working as his agent, similar to the Emperor’s Hand.

He tasked Callia with travelling to Bespin where she would investigate and collect a person of interest.

Promoted to Admiral after the destruction of Alderaan, Genarus Thorn continued to climb the political ladder by shrewd tactics and a willingness to work against his compatriots own interests. On Onderon he established a listening post to spy on his rival, Admiral Corlen.
